AUTOSTEREOSCOPIC DISPLAY DEVICE |
摘要 |
A switchable autostereoscopic display device comprises a display panel having an array of display pixels for producing a display, the display pixels being arranged in rows and columns, and a lens arrangement for directing the output from different pixels to different spatial positions to enable a stereoscopic image to be viewed, the lens arrangement being in a plane parallel to the display panel. The lens arrangement comprises an electrically switchable LC layer which defines a lens pattern or a lens replica pattern, wherein the LC alignment of the LC layer is electrically switchable such that the lens arrangement is switchable between a 2D mode and a 3D mode. In the 2D mode, the LC alignment is in a first direction substantially within the plane of the lens arrangement, and in the 3D mode the LC alignment is in a second, perpendicular direction also substantially within the plane of the lens arrangement. The light output of the display panel is polarized in the second direction. This arrangement enables a perpendicular relationship between the output of the display panel and the LC alignment direction to be maintained for two perpendicular viewing planes. |
